We also tested 92 ultrasound images of the liver cysts by our software. The corrected identification rate of the single liver cysts is 97.7 %, and that of multiple liver cysts is 87.5 %. Experimental results demonstrate that the proposed technique is reliable on segmenting the contour of liver...
Liver cystsare common, seen in 5% to 14% of the general population. They are thought to arise frombile ductepithelium. On ultrasound, cysts in the liver are anechoic, with sharp margins and enhanced through-transmission, analogous tobreast cysts. On both CT and MRI, they are homogeneous, ar...
Ultrasoundremains the imaging modality of choice for the diagnosis of liver cysts. Simple cysts are characteristically anechoic, well-defined, thin-walled (often imperceptible), oval or spherical lesions with no septations, and strong posterior wall acoustic enhancement. ...
We report a rare case of cystic metastases to the liver from a peripheral primitive neuroectodermal tumour in a child. Ultrasound and CT appearances are described with a discussion on the histological findings and the differential diagnosis.关键...
Perioperative hemodynamic management of refractory hypotension in a patient with giant hepatic cysts complicated by compression of the inferior vena cava Except simple hepatic cysts and polycystic liver disease which can be confidently diagnosed on the basis of ultrasound only, contrast-enhanced CT or MRI...
The visualisation of focal liver lesions on ultrasound: A review of 300 liver ultrasounds with CT or MRI correlationIntroduction Conventional ultrasound (US) is the most common imaging investigation of the liver. The ability of US to visualise focal liver lesions (FLLs) can be limited by ...
Pancreas cystsCystic lesions of the liver in the adult can be classified as developmental, neoplastic, inflammatory, or miscellaneous. Although in some cases... KJ Mortelé,PR Ros - 《Radiographics A Review Publication of the Radiological Society of North America Inc》 被引量: 789发表: 2001年...
Evaluation of diagnostic ultrasound as a mass screening technique for the detection of hydatid cysts in the liver and lung of sheep and goats Ultrasound examination of the liver and lung followed by post-mortem examination was performed in 16 sheep and 284 goats. Thirty-one (10.3%) were positiv...
Longitudinal oblique grayscale ultrasound of the right kidney using the liver as an acoustic window with the view obtained with more lateral angulation (when compared with the previous 2 images) cuts through the renal parenchyma on the lateral aspect of the right kidney. Note that the echogenic ...
It is frequently difficult to ascertain the exact nature of focal liver lesions discovered by ultrasound (US) because of the relatively broad overlap among the US appearances of such lesions. No image is completely pathognomonic. Cysts and small hemangio
